Swift is a powerful and intuitive programming language that is widely used for developing complex applications for iOS, iPadOS, watchOS, tvOS, and macOS. With its clean syntax and modern features, Swift makes it easy for developers to write high-performance, maintainable code. However, when it comes to developing complex applications, there are many advanced techniques that can be used to improve the overall architecture, performance, and maintainability of the codebase. In this blog, we will explore some of the most effective advanced techniques for complex apps in Swift.

Model-View-ViewModel (MVVM) Architecture

MVVM is a popular design pattern that is often used in Swift for complex applications. The pattern consists of three main components: models, views, and view models. The model is responsible for representing the data and state of the application, the view is responsible for presenting the data to the user, and the view model is responsible for bridging the gap between the model and the view. This architecture helps to keep the code organized, and it makes it easier to manage changes to the data and state of the application over time.

    func updateUI()
